| Abstract:A low molecular weight water-soluble phenolic resin was prepared by adding raw material in twice. The curing behavior of the phenolic resin was studied by DSC method. Mechanical properties of the cured filter paper impregnated with the phenolic resin were studied. Through the TGA thermogravimetric analysis,the best resin curing temperature was determined. By comparison of phenolic resin impregnation and curing process and filter paper properties, the experimental results indicated that the resol could be used for impregnating filter papers. The results showed that the burst index, dry tensile index and wet tensile index of filter paper impregnated with 20% phenolic resin could reach 1.53 kPa·m2/g, 30.1 N·m/g and 9.26 N·m/g, respectively. It was found that the water-soluble phenolic resin had little effect on the pore size and pore size distribution of the filter paper. The impregnated filter paper remained good pore structure. |
